integral from 2 to x of-2/(t^3)

\int_{2}^{x} - \frac{2}{t ^{3}} d t

\frac{1}{x ^{2}} - \frac{1}{4}

Solution steps

\int_{2}^{x} - \frac{2}{t ^{3}} d t

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - 2 \cdot \int_{2}^{x} \frac{1}{t ^{3}} d t

Apply the Power Rule

= - 2 [- \frac{1}{2 t ^{2}}]_{2}^{x}

Compute the boundaries:

- \frac{1}{2 x ^{2}} + \frac{1}{8}

= - 2 (- \frac{1}{2 x ^{2}} + \frac{1}{8})

Simplify

= \frac{1}{x ^{2}} - \frac{1}{4}
